ABSTRACT

Fundamental research on ageing has taken an interesting turn in recent years with the rapid development of biomarkers predicting mortality in model organisms, particularly Drosophila, as well as in humans through improvements in approaches to the identification of circulating molecules in mass. These developments lead to a shift in our ability to predict the occurrence of death from the historically population level to the individual level. We question here the ethical, medical and social implications of this change of scale.


TITLE: Conséquences éthiques et sociales de biomarqueurs prédictifs de la mort chez l'homme - La vieillesse et la mort, problématiques comportementales et sociétales. ABSTRACT: La recherche fondamentale sur le vieillissement a pris un tour intéressant ces dernières années avec un développement rapide des biomarqueurs prédictifs de mortalité chez les organismes modèles, notamment la drosophile, ainsi que chez l'être humain à travers les améliorations des approches d'identification en masse de molécules circulantes. Ces développements conduisent à un déplacement de notre capacité de prédiction de survenue de la mort, du niveau historiquement populationnel au niveau individuel. Nous interrogeons ici les implications éthiques, médicales et sociales de ce changement d'échelle.

ABSTRACT

Are diseases caused by aging? What are the mechanisms of aging? Do all species age? These hotly debated questions revolve around a unitary definition of aging. Because we use the word "aging" so frequently, both colloquially and scientifically, we rarely pause to consider whether this word maps to an underlying biological phenomenon, or whether it is simply a grab-bag of diverse phenomena linked more by our mental associations than by any underlying biology. Here, we consider how the presence of the colloquial word "aging" generates a cognitive bias towards supposing there is a unitary biological phenomenon. We ask what kind of evidence would support or refute that idea, and subsequently show clear evidence at multiple levels that aging is not a unitary phenomenon. In particular, the known aging pathways lead to heterogeneous outputs, not a single coordinated phenomenon. From levels ranging from cellular/molecular to clinical to demographic to evolutionary, we show how the supposition that aging is a unitary phenomenon can mislead and distract us from asking the best questions. For major sub-disciplines of aging biology, we show how going beyond the notion of unitary aging can hone the paradigm and help advance the pace of discovery.

ABSTRACT

It is common to find stigmatising terms being used to describe older people with dementia and / or living in care homes in the Brazilian literature, such as 'demented person', 'patient in asylum', or 'institutionalised elderly'. Historically, both mental illnesses and long-term care settings for older people have had negative connotations in society. The use of terms that historically refer to social segregation, institutionalization, or that reduce the individual to their disease can therefore contribute to the perpetuation of the stigma, prejudice, depersonalization and discrimination experienced by these people. This opinion paper aims to stimulate discussions about the use of such terms by the Brazilian scientific community and the media, as well as to foster reflections on the impact of the use of such language as part of current academic and clinical environments. The author mentions examples of stigmatizing phrases and words that are commonly found in the literature and mentions some of the consequences of stigma for people with dementia and those living in care homes. The author also refers to international documents which can be used as references for more inclusive and ethical writing.


É comum encontrarmos na literatura científica brasileira termos potencialmente estigmatizantes sendo utilizados para descrever pessoas com demência e pessoas vivendo em residenciais de cuidado, tais como os termos pessoa demenciada, paciente asilado ou idoso institucionalizado. Historicamente, transtornos mentais e residenciais de cuidado de longa duração para idosos detêm conotações negativas na sociedade. O uso de termos que historicamente remetem à segregação social, à institucionalização ou que reduzam o indivíduo à sua doença pode, portanto, contribuir para a perpetuação do estigma, do preconceito, da despersonalização e da discriminação frequentemente vividos por essas pessoas. Este artigo de opinião tem por objetivo fomentar discussões sobre o uso de tais termos pela comunidade científica brasileira e pela mídia, bem como refletir sobre o impacto do uso de tal linguagem como parte das culturas acadêmica e clínica atuais. A autora cita exemplos de frases e palavras estigmatizantes que são comumente encontradas em publicações brasileiras e aponta algumas das consequências do estigma para as pessoas com demência e aquelas que vivem em residenciais de cuidados. A autora também menciona documentos internacionais que podem ser utilizados como referência para uma escrita mais inclusiva e ética.

ABSTRACT

What if science enabled us to live an extended lifespan? Well, not us, but people in the future, and perhaps not everybody in the future, at least not at first. Should we allow and encourage science to develop this capability, or should we try to prevent or inhibit it? John Davis's book New Methuselahs: The Ethics of Life Extension is a thorough exploration of these questions. He presents the arguments for and against developing this capacity, and he considers three perspectives: those of individuals who will be able to extend their lives (the Haves), individuals who will not because they can't afford to (the Have-nots), and individuals who will not extend their lives because they are opposed to doing so (the Will-nots). Davis is a philosopher, and the bulk of this book is for the cognoscenti.

ABSTRACT

Humans have long been troubled by the prospect of old age and its culmination in death. Whether to rebel against or accept this fate have been wrestled with down through the centuries. But new medical technologies and the growing science of aging have sided with rebellion. We know that aging can be pushed back and improved in its quality. That progress is well under way, but now intensified by many scientists and Silicon Valley entrepreneurs. In 2016, Mark Zuckerberg and Priscilla Chan pledged three billion dollars toward eventually "preventing, curing or managing all diseases." And some visionaries have made the elimination of death or its indefinite postponement a goal. To put those aspirations in a broader context, it is helpful to keep in mind where population growth and aging trends stand. Apart from any success in the explicit efforts to increase longevity, there will be a steady increase in the number of elderly worldwide-and a much higher percentage of the elderly as part of the overall population. Most of the largest changes will be in developing countries. They will be overburdened by the death of the elderly from expensive chronic diseases-already a vexing problem for affluent countries.

ABSTRACT

The survival of large segments of human populations to advanced ages is a crowning achievement of improvements in public health and medicine. But, in the 21st century, our continued desire to extend life brings forth a unique dilemma. The risk of death from cardiovascular diseases and many forms of cancer have declined, but even if they continue to do so in the future, the resulting health benefits and enhanced longevities are likely to diminish. It is even possible that healthy life expectancy could decline in the future as major fatal diseases wane. The reason is that the longer we live, the greater is the influence of biological aging on the expression of fatal and disabling diseases. As long as the rates of aging of our bodies continues without amelioration, the progress we make on all major disease fronts must eventually face a point of diminishing returns. Research in the scientific study of aging has already showed that the aging of our bodies is inherently modifiable, and that a therapeutic intervention that slows aging in people is a plausible target for science and public health. Given the speed with which population aging is progressing and chronic fatal and disabling conditions are challenging health care costs across the globe, the case is now being made in the scientific literature that delayed aging could be one of the most efficient and promising ways to combat disease, extend healthy life, compress morbidity, and reduce health care costs. A consortium of scientists and nonprofit organizations has devised a plan to initiate an accelerated program of scientific research to develop, test for safety and efficacy, and then disseminate a therapeutic intervention to delay aging if proven to be safe and effective; this is referred to as the Longevity Dividend Initiative Consortium (LDIC). In this review, I articulate the case for the LDIC.

ABSTRACT

If the prediction of some scientists comes true, then we are only few years away from the appearance of the first generation of human beings who will be able to add one year to each remaining year of life expectancy. Faced with this possibility, it seems appropriate to give thought to the public policies that should be adopted. It is better to anticipate the various future scenarios than react to a reality which is a fait accompli. To date, the debate has mainly focused on the ethical question: is it good or bad for us humans to achieve immortal life? Until now, neither legal guidelines at State level nor those of international organisations which deal with bioethical issues have concerned themselves with this matter. But before discussing policies, two other matters should be addressed: first, to show how the prolongation of human life can be as much the unwanted outcome of legitimate efforts in search of healthy aging, as one of the aims of the post-humanist project; second, to present the most consistent and shared ethical reasons for rejecting the human immortality project


Si el vaticinio de algunos científicos se llega a cumplir, nos quedan unos pocos años para que urja la primera generación de seres humanos que conseguirá incrementar un año de vida por año de esperanza de vida que le quede. Ante esta posibilidad, es conveniente pensar en las políticas que deberían adoptarse. Es mejor anticiparse a los diversos escenarios futuros que reaccionar ante realidades ya consumadas. Hasta el momento, el debate se ha centrado principalmente en la cuestión ética: ¿es bueno o malo para el ser humano alcanzar una vida inmortal? Ni las normas jurídicas de los Estados ni de los organismos internacionales que tratan de cuestiones bioéticas se han ocupado directamente de esta cuestión. Pero antes de hablar de políticas conviene tratar otros dos asuntos. Primero, mostrar cómo la prolongación de la vida humana puede ser tanto el resultado no buscado de los legítimos esfuerzos por conseguir un envejecimiento saludable, como una de las metas del proyecto posthumanista. Y segundo, presentar las razones éticas más consistentes y compartidas para rechazar el proyecto de inmortalidad humana

ABSTRACT

Despite the common apprehensions regarding the aging population, this work aims to argue, on both deontological and utilitarian moral grounds, that any increase in general life-expectancy will be beneficial for the Middle East, countering the common fears associated with this increase. A set of ethical arguments concerning increasing longevity is presented, from both the deontological and utilitarian perspective. A wide selection of economic, psychological, demographic and epidemiological literature and databases is analyzed to determine common correlates of extended longevity. On the deontological grounds, the value of extended longevity is derived from the value of life preservation, regardless of its term. On the utilitarian grounds, the value of extended longevity is demonstrated by its correlation with further human values, such as education level and intellectual activity, economic prosperity, equality, solidarity and peacefulness. With the common apprehensions of stagnation and scarcity due to life extension found wanting, the pursuit of longevity by the population can be seen as a cross-cultural and cross-generational good. Though the current study mainly refers to sources and data relevant to the Middle East, a similar pro-longevity argument can be also made for other cultural contexts. In view of its numerous benefits, normatively, the goal of longevity should be set clearly and openly by the society, and actively pursued, or at least discussed, in academia, the political system and broader public.

ABSTRACT

Se realizó una investigación descriptiva y longitudinal en adultos mayores pertenecientes al Consultorio Médico 40 del Policlínico Epifanio Rojas Gil del Municipio San Luís, Provincia Pinar del Río durante el 2007. Con el objetivo de aplicar un programa de intervención educativa a los ancianos, para modificar conocimientos y estilos de vida. El universo estuvo constituido por 129 adultos mayores y la muestra por 109 que cumplieron los requisitos de inclusión. La información se obtuvo a partir de una encuesta y el instrumento para evaluar el funcionamiento familiar. Los resultados obtenidos fueron llevados a tablas estadísticas para realizar un análisis, a los cuales se les aplicó Técnicas de Estadística Descriptiva (números absolutos, porcientos) y prueba de hipótesis de comparación de proporción para el nivel de significación 0,05, para demostrar que se reducen las actividades perjudiciales relacionadas con el ritmo de vida después de la intervención educativa. Se incrementaron los conocimientos relacionados con los hábitos perjudiciales para la salud con la estrategia intervencionista. Disminuyeron los estilos de vida dañinos al incrementar los conocimientos sobre temas de salud con la capacitación. Se logró disminuir la ingestión de alimentos dañinos e incrementar la de los alimentos saludables con la intervención educativa y el funcionamiento familiar moderadamente funcional resultó ser la mayor percepción en los ancianos. La Intervención Educativa se considero muy satisfactoria por los resultados estadísticos obtenidos para lograr una Longevidad Satisfactoria...(AU)


A descriptive and longitudinal research was conducted with the elderly belonging to the Medical Office (No-40) at Epifanio Rojas Gil outpatient clinic in San Luis municipality, Pinar del Rio province during 2007. This research was aimed at applying a program of educational intervention to the elderly in order to increase knowledge and modify life styles. The target group was comprised of 129 old people and the sample with 109 having the criteria of inclusion. The information was collected from a survey and the tool to evaluate family function. The results obtained were described in statistical tables to complete the analysis. Descriptive statistics (absolute numbers, percentages) and the hypothesis test for the comparison of proportion to 0,05 level of significance were used to demonstrate that risky activities related to the pace of life after the educational intervention decreased . Knowledge related to the recognition of harmful health habits increased with the application of this intervention strategy. Negative life styles decreased with the increase of knowledge. Hazardous food consumption decreased and the ingestion of healthy food increased with the educational intervention. Moderately family function resulted in a major perception of the elderly. The educational intervention was very satisfactory due to the results achieved to accomplish a satisfactory long life...(AU)

ABSTRACT

Debates about the ethical and social implications of research that aims to extend human longevity by intervening in the ageing process have paid little attention to the attitudes of members of the general public. In the absence of empirical evidence, conflicting assumptions have been made about likely public attitudes towards life-extension. In light of recent calls for greater public involvement in such discussions, this target article presents findings from focus groups and individual interviews which investigated whether members of the general public identify ethical issues surrounding life-extension, and if so, what these ethical issues are? In this study, while some participants were concerned primarily with the likely personal consequences of life-extension, for others the question of whether or not to pursue interventions to extend longevity, and how they should be implemented, clearly raised important ethical issues, many of which have been prominent in debates among bioethicists.

ABSTRACT

There are a number of ethical, social, and personal implications generated by the potential development and use of technologies that may extend human longevity by intervening in aging. Despite speculations about likely public attitudes toward life extension, to date there have been few attempts to empirically examine the public's perspective of these issues. Using open-ended survey questions via telephone interviews, this study explored the attitudes of 605 members of the Australian public toward the implications of life extension. Participants were asked to briefly describe in their own words what they believed would be the beneficial, as well as negative, implications arising from life extension (if there were any), both for themselves personally and for society as a whole. Participants were also asked to describe any ethical concerns they had about life extension, if they had any at all. All open-ended responses were collated and then underwent a thematic analysis to uncover commonly cited issues regarding personal benefits/negatives, societal benefits/negatives, and ethical concerns. A considerable number of participants envisioned at least some beneficial as well as negative implications for themselves and for society, and many claimed to have at least some ethical concerns. Some novel issues were raised as well as a number of those discussed within the bioethical literature. The results should encourage researchers, bioethicists, and policy makers to engage with members of the public about the goals of research surrounding life extension, the expected outcomes of such research, and the likely implications for individuals and society.

ABSTRACT

The fair innings argument maintains that for healthcare resources to be distributed fairly every person should receive sufficient healthcare to provide them with the opportunity to live in good health for a normal span of years. What constitutes a normal span of years is often defined as life expectancy at birth, but this criterion fails to provide adequate grounds for the equal distribution of healthcare across and between generations. A more suitable criterion for the normal life span is the idea that the human life span is biologically limited. Many current gerontological theories argue that the biological limit to human life spans is related to the ageing process. If technological advances in medicine can retard the ageing process by treating and preventing the diseases and disorders associated with it, human longevity will be limited only by the developments in and the successful application of medicine. In consequence, the fair innings argument will no longer be able to justify denying people healthcare resources because they have lived longer than the normal life span.
